"The scientific method," Thomas Henry Huxley once wrote, "is nothing but the normal working of the human mind." That is to say, when the mind is working; that is to say further, when it is engaged in corrrecting its mistakes. Taking this point of view, we may conclude that science is not physics, biology, or chemistry-is not even a "subject"-but a moral imperative drawn from a larger narrative whose purpose is to give perspective, balance, and humility to learning.
